CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 400,563, dated A ril 2, 1889. Application filed January 2W1, 1889. Serial No. 297,084. (No model.)

To all whom it may concern.-

Be it known that I, WILEY M. GRISHAM, of Winchester, in the county of Scott and State of Illinois, have invented a new and useful Improvement in Oar-Couplings, of'which the following is aspecification.

My invention is an improvement in carcouplings; and it consists in the novel construction and combination of parts hereinafter described, and pointed out in the claims.

By my invention I seek to provide improvements in the draw-head and in the couplingpin and its operating mechanism, as will more fully appear from What follows.

In the drawings, Figure 1 is a perspective view of myimprovement on the end of a car. Fig. 2 is a section on about line a: 00, Fig. 1. Fig. 3 is a cross-section on about line y y, Fig. 1. Fig. 4 is a section on about line 2 z, Fig. 3; and Fig. 5 is a detail view of the coupling-pin.

The draw-head A is in practice suitably secured to the car. In its forward end the said draw-head is shown with a central link, mortise, or recess, B, to receive the ordinary coupling-link, an opening, I), for the ordinary coupling-pin being formed to enter said mortise B, as shown. The coupling-hook O is pivoted to the draw-head, and the mortise D for the hook O on the meeting draw-head is formed in said draw-head on opposite sides of the mortise B, so that the hook C on one of two meeting draw-heads will enter the mortise or Way D on the other draw-head. The hook O is pivoted at c to the, draw-head A, and has the hook proper, O, at its outer free end bent downward, as shown.

The mortise or wayD has its lower wall inclined at cl at its forward end up nearly to the transverse pin-opening E, and at d( in rear of such pin-opening down therefrom I cover the mortise or way D with a shield or cover, F, as shown. The pin-opening E, as shown, is

"'"fwmed. .transversely of the draw-head and above and slightly in rear of the crown of inclines d d, and is provided with a slot-like extension, 6, which is formed at an incline coincidin g with incline (Z and extending down to about the upper end of such incline d, as shown. The pin G is movable longitudinally in the opening E, and is provided with a radial lug or wing, g, fitted to the extension or slot 6 of opening E, and which in the coupled position of the pin forms an extension of the hook-incline d, as will be readily understood from the drawings.

To operate the pin G, I provide on its upper side, near its end opposite that provided with lug g, arack or series of cog-teeth, G, which are meshed by a cog-wh eel, I-I, journaled to the draw-head and operating in a slot, I, leading upward from the opening E. This wheel H is provided with a handle, 71, being usually formed with a socket to receive such handle, so it may be applied and removed at will.

I The operation will be readily understood. By means of the central link-mortise the coup ling with an ordinary draw-head may be ef= fected by means of the common link and pin. a

In the use of the hook C such hook will enter its way, pass up incline d, thence onto the lug or wing g, the pin G being in closed position, and will ride up wing 9 onto and over the pin G, and engage the same to effect the coupling, which may be released by withdrawing the pin G. This may be conveniently effected by the aid of the rack and toothed wheel before described. The incline (1', leading from the rear up to the top of incline d, prevents any stopping of the hook when the pin G is withdrawn, and guides the hook directly up to the top of the incline.

Having thus described my invention, what I claim as new is 1. In a car-coupling, the draw-head having a way for the coupling-hook formed with an incline up which to direct such hook, and having a transverse horizontal opening or guide for the coupling-pin, and the coupling-pin movable in said guide and provided with a flange or wing arranged in the closed position of the pin to form an extension or continuation of'the incline for the coupling-hook, substantially as set forth.

2. The combination of the draw-head having a Way for the coupling-hook and a transverse guide or opening for the coupling-pin, the coupling-pin having a rack or series of teeth, and the toothed wheel, substantially as and for the purposes specified.

3. In a car-coupling, the draw-head having a transverse guide or opening for the coupling-pin and formed with an incline, d, leading up thereto, and with an incline, d, leading rearwardly and down from the upper end of incline d, combined With the coupling-pin, substantially as set forth.

l. The improvement in ear-couplings,eomprising the draw-head having away for the coupling-hook formed with an inclined bottom and having a transverse pin-opening, E, formed with a slot-like extension, e, and the coupling-pin having a Wing or flange, g, all substantially as set forth. I

5. The improved car-coupling herein described, comprising the draw-head having opening E formed With extension 6, the Way 1 D, having inclines d d, and a shield or cover, F, and the central link-mortise, the couplinghook pivoted to said draw-head, the couplingpin G, having flange or wing g and provided with the rack or teeth, and the toothed operating-wheel meshing said teeth, substantially as set forth.
